Housewife Alison Blackburn was in so much pain from the spider bite on her foot that she was rushed to hospital where she had to have the poison DRAINED from her.

Now Ms Blackburn is terrified of sleeping in her own bed in case she gets bitten by the spider - which wasn't caught - again.

The 49-year-old woke with a start at 4am earlier this month, complaining of a sharp pain in her stomach.

Partner Gary Pelatt noticed her foot was red, and within hours, her foot and ankle had swollen so much she could not get her shoe on.

Ms Blackburn said: "By this time I was feeling very unwell.

"I kept going hot and then cold. I was shivering and I was in a lot of pain."

When the swelling got even worse, she was rushed to hospital where docs prescribed her antibiotics - but a rash developed along with the swelling and it was decided that her foot needed to be drained of the false widow poison.

She revealed: "I felt so sick. I had pins and needles in my leg. It was throbbing. I was slurring my words.
